2. Place a 1/2 in. drive wrench in the 1/2 in. square
hole in the eccentric plate use it to hold the
eccentric plate when the adjustment bolt is
loosened in the next step.
3. Loosen the adjustment bolt for the eccentric plate
and use the 1/2 in. drive wrench to slowly raise the
eccentric plate to its highest position and release
the belt tension.
4. Remove the belt from the cross shaft/engine pulley
and the idler pulleys.
5. Support the compressor and unbolt the compressor
mounting flange from the engine (leave the
refrigeration lines connected).
6. Slide the compressor assembly away from the
engine.
7. Remove the belt through the gap between the
compressor coupling and the flywheel.
8. Install the new belt on the compressor coupling
through the gap between the compressor coupling
and the flywheel.
9. Slide the compressor back into position and install
the mounting bolts.
10. Use use the 1/2 in. drive wrench to slowly raise the
eccentric plate its highest position.
11. Place the new belt on the cross shaft/engine pulley
and idler pulleys. Verify the belt fits on the pulleys
correctly and is fitted correctly into the grooves in
the grooved pulleys.
12. Use use the 1/2 in. drive wrench to slowly lower the
eccentric plate against the belt pressure until the
Gauge Tool P/N 2042436 fits over the heads of the
spring damper strut bolts.

ntt:: Care must be taken when installing the belt
to ensure it s correctly seated in pulley
grooves. The belt will be damaged if the
correct installation into the pulley grooves
is not observed. The belt only has to be out
of place on the grooved idler by one groove
for it to fail.

ntt:: The gauge tool must not be locked on the
bolt heads but must move freely on and off
the bolt heads. The center to center
dimension of 5.472 in. (139.0 mm) between
the bolt heads of the spring damper strut is
verified using Gauge Tool P/N 2042436,
which is a checking gauge not a setting
gauge and should not be used to hold the
spring damper strut in position prior to
tightening the holding hardware.

13. Once the gauge tool fits perfectly and freely on the
screw heads of the spring damper strut, remove it
and tighten the adjustment bolt and the pivot bolt
to lock the eccentric plate in that position.
14. Place the gauge tool over the heads of the spring
damper strut bolts again to verify the setting is
correct.
15. Remove the gauge tool and torque the strut bolts to
20–24 ft-lbs (27 to 33 N•m).
